BEDSTEAD-FASTENING.

Specification of Letters Patent No. 5,689, dated August 1, 1848.

To all whom t may concern.'

Be it known that we, JOHN A. JONES and ALFRED F. JONES, of Lexington, inthe county of Fayette and State of Kentucky, have invented a new andImproved Manner of Connecting the Rails and Posts of Bedsteads to EachOther; and we do hereby declare the following to be a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, making a part of this specification.

Ve make round perforations inL two sides of each post, and inserttherein the rods K,-passing them transversely through the center of eachperforation. Into each end of the rails we insert and secure the shankof a round projecting bolt head,-shown in the drawings ,-the peripheryof which fits into either of the perforations in the posts. Ve form anarrow slit entirely across the center of the face of each bolt head,and

continue an opening inward therefrom, in a winding direction, nearly tothe base of the head. Vhen the bolt heads (projecting from theextremities of the rails) are inserted into the perforations in theposts, the transverse retaining rods K,-(pa`ssing across theperforations) will enter the openings in the bolt heads, and as therails are turned, the winding direction of these openings,-serving asdouble inclined planes,- will take hold of the retaining rods` and drawthe ends of the rails firmly against the sides of the posts.

This operation of the inclined planes and pin considered as a mechanicalaction is not claimed to be new, but only when applied in this manner,Viz: two inclined planes within a round bolt head which serves thepurpose of a tenon lfor support, as well as to effect the tighteningoperation.

We do not claim simply fastening the posts and rails by the operation ofthe pins and the inclined surfaces within the proecting bolt heads atthe ends of the rails;

Vhat we do claim as our invention, and desire to secure by LettersPatent, is-

The securing the rails to the postsof bedsteads, by means ofperforations in the posts traversed by retaining rods and combined withthe bolt heads,-constructed in the manner described,-projecting from theends of the rails; that is to say, each bolt head being divided by aslit for the reception of a retaining rod,-which slit as it eX- tendsinward, winds or twists, forming double inclined planes (one on eachside of the slit) that actupon a retaining rod as the rails are turned,and draw and secure the end of each rail, firmly to its post, while thebolt head serves also in itself the purpose of a tenon to give strengthto the joint.
